More than 230 million people have tested positive for severe acute respiratory syndrome-coronavirus-2 infection globally by September 2021. The infection affects primarily the function of the respiratory system, where ∼20% of infected individuals develop coronavirus-19 disease (COVID-19) pneumonia. This review provides an update on the pathophysiology of the COVID-19 acute lung injury. ⋯ This review summarises the fundamental pathophysiological features of COVID-19 in the context of the respiratory system. It provides an overview of the key clinical manifestations of COVID-19 pneumonia, including gas exchange impairment, altered pulmonary mechanics and implications of abnormal chemical and mechanical stimuli. It also critically discusses the clinical implications for mechanical ventilation therapy.

Observational Study
Variant-dependent heterogeneity in amyloid β burden in autosomal dominant Alzheimer's disease: cross-sectional and longitudinal analyses of an observational study.
Insights gained from studying individuals with autosomal dominant Alzheimer's disease have broadly influenced mechanistic hypotheses, biomarker development, and clinical trials in both sporadic and dominantly inherited Alzheimer's disease. Although pathogenic variants causing autosomal dominant Alzheimer's disease are highly penetrant, there is substantial heterogeneity in levels of amyloid β (Aβ) between individuals. We aimed to examine whether this heterogeneity is related to disease progression and to investigate the association with mutation location within PSEN1, PSEN2, or APP. ⋯ National Institute on Aging, Doris Duke Charitable Foundation, German Center for Neurodegenerative Diseases, Japanese Agency for Medical Research and Development.

An 85-year-old Japanese man, who was taking aspirin and edoxaban for previous myocardial infarction and atrial fibrillation, came to our hospital with a chief complaint of dyspnea for 3 weeks. Chest radiography showed a massive left pleural effusion (Fig 1A). ⋯ However, he had neither coagulation disorder nor thrombocytopenia, and the pleural effusion was negative for atypical cells. These findings suggested that the antithrombotic and anticoagulant medications might have induced the hemothorax.

ReviewShould fluid management in thoracic surgery be goal directed?
To find a reliable answer to the question in the title: Should fluid management in thoracic surgery be goal directed? ⋯ Although the evidence level is low, GDT is generally associated with fewer postoperative complications. It can be helpful in decision-making for volume-optimization, timing of fluid administration, and indication of vasoactive agents.
